Prevalence of Obesity, Prediabetes, and Diabetes in Sexual Minority Men: Results From the 2014 Behavioral Risk Factor Surveillance System

Higher Risk of Many Physical Health Conditions in Sexual Minority Men: Comprehensive Systematic Review and Meta-Analysis in Gay- and Bisexual-Identified Compared with Heterosexual-Identified Men

Purpose: The purpose of this study was to provide a systematic review and, where possible, meta-analysis on the prevalence of physical health conditions in sexual minority men (SMM, i.e., gay- and bisexual-identified men) compared with heterosexual-identified men. Methods: A systematic literature search in the databases MEDLINE, Embase, CENTRAL, CINAHL, and Web of Science was conducted on epidemiological studies on physical health conditions, classified in the Global Burden of Disease project and published between 2000 and 2021. Meta-analyses comparing odds ratios were calculated. Results: In total, 23,649 abstracts were screened, and 32 studies were included in the systematic review. Main findings were that (1) Largest differences in prevalence by sexual identity were found for chronic respiratory diseases, particularly asthma: overall, SMM were significantly almost 50% more likely to suffer from asthma than heterosexual men. (2) Evidence of higher prevalence was also found for chronic kidney diseases and headache disorders in gay men and for hepatitis B/C in both gay and bisexual men. (3) We found an overall trend that bisexual men were more affected by some of the physical health conditions compared with gay men (e.g., cardiovascular diseases, asthma). However, regarding cancer, headache disorders, and hepatitis, gay men were more affected. Conclusion: We found evidence of physical health disparities by sexual identity, suggesting more health issues in SMM. Since some of these findings rely on few comparisons or small samples of SMM only, this review is intended to be a vehement plea for routinely including sexual identity assessment in health research and clinical practice.

Exploring Sexual Orientation Disparities Regarding the Interplay of Childhood Sexual Abuse, Self-Reported Diabetes Status, and Depression Among Adults in the United States

Previous research has revealed a strong link between the experience of childhood sexual abuse (CSA) and diabetes in adulthood. Moreover, research has shown that sexual minorities (SM) are exposed to adverse childhood experiences (ACEs) (i.e. CSA) and experience depression at higher rates than their heterosexual counterparts. Thus, it is imperative to further investigate the role of depression and the differential associations of exposure to ACEs with diabetes prevalence by sexual orientation. We explored sexual orientation disparities regarding the relationship between CSA and diabetes and examined the moderating role of depression. A total of 29,903 participants from the 2021 Behavioral Risk Factor Surveillance System (BRFSS) were included in this study. Secondary data analysis was conducted using the survey data, and weighted logistic regression and moderation analysis were performed. Heterosexuals who experienced CSA (AOR = 1.25; p < .05) and SM who experienced CSA (AOR = 2.13; p < .05) reported higher odds of having diabetes. Among heterosexuals, depression (AOR = 1.38; p < .001) was significantly associated with having diabetes. Additionally, depression was a significant moderator among heterosexuals with and without CSA. Further understanding of the impact of ACEs on diabetes among specific subgroups of SM should be assessed in future studies.

Paradoxical Obesity and Overweight Disparities Among Sexual Minority Men: A Meta-Analysis

This study aims to analyze the prevalence and likelihood of overweight, obesity, and elevated body mass index (BMI) among sexual minority men (i.e., men who have sex with men [MSM], men who have sex with men and women [MSMW], and all sexual minority men), using men who have sex with women (MSW) as the reference group. Studies reporting mean BMIs or prevalence or likelihood of obesity, overweight, or elevated BMI categorized by sexual orientation were included. Data were pooled and analyzed to report mean differences (MDs) of BMIs, prevalence rates, odds ratios (ORs), and their respective 95% confidence intervals (CIs). Forty-three studies were included, with a median of 26,507 participants (median 3.37% sexual minority men). The respective mean overweight, obesity, and elevated BMI prevalence rates among MSM (36%, 23%, and 39%) and MSMW (33%, 27%, and 47%) were lower than those of MSW (44%, 26%, and 55%). This finding was consistent with a significantly lower BMI (MD −1.50 [−1.93, −1.08] kg/m²) and a decreased likelihood of overweight (OR 0.75 [0.64, 0.88]) and obesity (OR 0.84 [0.78, 0.90]). Sexual minority men present with a lower prevalence and likelihood of obesity and overweight than their heterosexual counterparts. The obesity paradox—a sustained catabolic state presenting with lower BMI—is a feasible explanation for this phenomenon, although further research exploring paradoxical cardiovascular findings is granted.

Comorbidity Prevalence and Impact on Quality of Life in Gay and Bisexual Men Following Prostate Cancer Treatment

Introduction

Studies have demonstrated worse health related quality of life (HRQOL) outcomes in gay and bisexual men (GBM) following prostate cancer treatment compared to heterosexual men potentially due to differences in comorbidity burden.

Aim

To establish the prevalence of comorbidities and their association with HRQOL metrics in GBM following prostate cancer treatment.

Methods

We evaluated HRQOL and prevalence of comorbidities in 193 GBM from the United States and Canada in a cross-sectional, online survey: the Masked for Review. HRQOL was measured with the Expanded Prostate Cancer Index Composite (EPIC) and the 12-Item Short Form Health Survey (SF-12).

Main Outcome Measures

Our outcomes included comorbidity prevalence, mean differences for HRQOL scores by comorbidity status, and mean differences for HRQOL by comorbidity count.

Results

GBM were found to have a higher prevalence of blood vessel disease and mental health disorders but lower prevalence of obesity and type 2 diabetes when compared to published data in general prostate cancer populations. Statistically significant reductions in HRQOL metrics were associated with mental health diagnoses, diabetes, and obesity. Increased number of comorbidities was also associated with reductions in HRQOL metrics in nearly all categories.

Conclusion

These results suggest that the worse QOL outcomes in GBM following prostate cancer treatment may be due to differences in comorbidity burden. This study is the first to evaluate the relationship between comorbidities and HRQOL outcomes in GBM. Limitations of this study include a small sample size and cross-sectional study design. If confirmed in larger, longitudinal, clinically confirmed studies, these findings indicate a need to intervene on and consider comorbidities in GBM diagnosed with prostate cancer.

Factors associated with obesity in the Pharmacokinetic and Clinical Observations in People over Fifty (POPPY) cohort: an observational cross-sectional analysis

OBJECTIVES

The aims of the study were to describe the prevalence of obesity in the Pharmacokinetic and Clinical Observations in People over Fifty (POPPY) cohort, to identify demographic, clinical and HIV-specific factors associated with obesity, and to characterize the association between obesity and sociodemographic, clinical and HIV-specific factors and quality of life (QoL).

METHODS

A cross-sectional analysis was carried out of baseline data from the three groups ["older" people with HIV infection (PWH) aged ≥ 50 years, "younger" PWH aged < 50 years and HIV-negative controls aged ≥ 50 years] within the POPPY cohort. Obesity was defined as a body mass index (BMI) > 30 kg/m² .

RESULTS

A total of 1361 subjects were included in the study, of whom 335 (24.6%) were obese. The prevalence of obesity was higher in controls (22.3%) than in older (16.8%) and younger (14.2%) PWH, with no differences between the two groups of PWH. Factors associated with obesity were older age, female gender, black African ethnicity and alcohol consumption. Recreational drug use and a higher current CD4 T-cell count (in PWH) were associated with lower and higher odds of being obese, respectively. The presence of obesity was associated with worse physical health QoL scores, higher odds of having cardiovascular disease, type 2 diabetes and hypertension, but lower odds of having osteopenia/osteoporosis, irrespective of HIV status.

CONCLUSIONS

Despite a lower prevalence of obesity in PWH, specific subgroups (women, people of black African origin and older people) were more likely to be obese, and negative health consequences of obesity were evident, regardless of HIV status. Whether targeted preventive strategies can reduce the burden of obesity and its complications in PWH remains to be determined.

Overweight and Obesity among Sexual Minority Adults in the United States

There is evidence that sexual minority populations have a potentially heightened risk of poor health outcomes due in part to the discrimination they may face. In the present study, we examined whether overweightness and obesity vary by sexual minority subgroup using a large, nationally representative sample. Data were drawn from 2014–2017 Behavioral Risk Factor Surveillance System (BRFSS) surveys (n = 716,609). We grouped participants according to sexual identity (straight, lesbian or gay, bisexual, and other/don’t know/not sure). The propensity score matching technique was used to address covariate imbalance among sexual identity groups. In addition, subgroup analyses were performed for both males and females. Compared to straight adults, lesbian females had significantly higher odds of being overweight (OR (odds ratio) 1.33; 95% CI (confidence interval) 1.17–1.53), whereas gay males had significantly lower odds (OR 0.66; 95% CI 0.59–0.73). Similarly, lesbians were more likely to be obese (OR 1.49; 95% CI 1.31–1.70), whereas gay men had significantly lower odds of obesity (OR 0.77; 95% CI 0.69–0.86) when compared to straight adults. Bisexual females had significantly higher odds of being overweight (OR 1.21; 95% CI 1.10–1.34) and obese (OR 1.43; 95% CI 1.29–1.59), whereas bisexual males showed no significant difference. Our results strengthen previous findings and further highlight the need for research by sexual minority subgroup.

Differential Influence of Weight Status on Chronic Diseases by Reported Sexual Orientation Identity in Men

PURPOSE

This study examined whether the association between weight status and four chronic diseases (heart disease, hypertension, lifetime asthma, and type 2 diabetes) varied according to sexual orientation identity among adult men, controlling for demographic, socioeconomic, and other factors.

METHODS

Pooled data from male adult participants (n = 72,214) in the 2003-2012 California Health Interview Survey were used along with logistic regression models to estimate whether the associations between weight status and chronic diseases varied by sexual orientation identity.

RESULTS

Weight status was positively associated with each of the chronic diseases (hypertension, heart disease, asthma, and diabetes) among both gay and bisexual men and heterosexual men; however, the associations varied significantly by sexual orientation identity. Among gay and bisexual men, the associations were stronger and statistically significant-with the exception of lifetime asthma-particularly for men in the obese classifications, before and after controlling for age, marital status, race/ethnicity, education, income, health insurance status, food security level, smoking, and nativity.

CONCLUSIONS

Weight status had stronger detrimental associations with chronic disease among gay and bisexual men despite these men having greater socioeconomic advantage and lower body mass index than heterosexual men. Future research should examine mechanisms, including stress related to minority status, which may lead to greater risks for chronic diseases among sexual minority men.
